For sale are my Mystery Pokemon Slabs.
Each pack is guaranteed to contain at least one PSA 9/ACE 9 or higher (many grade 10s are inside some of these packs). All ACE graded cards have the ACE premium label. 
Multiple hit cards have been included with the most expensive being worth £120. I have also randomly put some additional raw holo cards and sealed booster packs into some of them.
All packs have been heat sealed and randomly mixed up so I do not know the location of the hits. Expect to see contents like modern illustration rares, full arts & special illustration rares. 90% of the packs contain English cards, the remaining 10% are Japanese.
I do these each year as a bit of fun and want them to be enjoyable to open regardless of whether you get a big hit or not. I believe that they are the fairest packs available online and I do not make any profit above what the cards would sell for individually! I pride myself in being one of the longest standing and most trustworthy Pokemon stores in the UK.
